Covinax 525-00 is surfactant stabilized

Covinax 525-66 DEV


COVINAX 525-66 DEV is a surfactant stabilized vinyl acrylic copolymer emulsion developed for high performance permanent pressure sensitive adhesive applications. It has an excellent balance of peel adhesion and shear adhesion. COVINAX 525-66 DEV is internally cross linked, giving it superior cohesive strength. In addition, it has been tested on vinyl film used in digital graphics applications and exhibits good plasticizer migration resistance. It will resist cold flow and will die cut and convert well, giving dry edges to finished sheets and rolls.
